The object of the invention-is to provide e wheel for nse-in-marlnngmachines of t is characterlwhichfian,being:- pensively manufactured and which will stand up" nnderthe usage to whlch 1t is put. In order togive onnnderstandingpi our invention, we have illustrated m the drawa selected embodiment thereoi which a in wfil now be described, after which the novel features will be pointed out in theappended claims.

Fig. 2 is an edge view of the type wheel; Fig. 8 is a. section on the line 3-3, 1; Fig. 4 is a section on the line H, Ft I; Fi 5 is a perspeetiveview of one o the type-hearing members;

ig. 6 is a perspective view of a'filling member.

We have found from experienceth'at c type wheel in which the type-bearing portions are made of die casting is an extremely serviceable and satisfactory type wheel. 'It

is, however, difficult to make n relatively large 1pc wheel from a single die casting,-

part1 cause of the-manner in which (he castings are made. Moreover, if a relatively is made in a single a casting, ere is alwaysdanger that e e wheel will warp or twist somewhat, us throwing the type characters out ofv correct alinement and making the wheel lmdesirablej n-, iectim ressionisdesiredn-w Fr B My oitizensnof -t e United vStates, and res d nts of- Keen county o-Cheshire, State o-,New,.,Haa;np
